電纜橋架選型導(dǎo)航
一、電纜橋架產(chǎn)品體系
電纜橋架產(chǎn)品體系包括:結(jié)構(gòu)形態(tài)、原材料、表面處理。
結(jié)構(gòu)形態(tài)包括:盤式、梯式、槽式。
原材料包括: 鋁合金、鋼制、玻璃鋼、復(fù)合型。
表面處理包括:熱鍍鋅、電鍍鋅、噴塑、鍍鋅加噴塑。
二、電纜橋架適用場(chǎng)合
槽式電纜橋架屬于封閉式電纜橋架。此種電纜橋架對(duì)電纜的屏蔽干擾和防腐蝕有較好的作用,適合雨計(jì)算機(jī)機(jī)房等。
盤式電纜橋架具有重量輕、散熱方便等特點(diǎn),適合于化工、石油、電訊電視等方面。
梯式電纜橋架具有年散熱效果好、成本低的特點(diǎn),適用于大直徑電纜敷設(shè)。
鋁合金電纜橋架具有重量輕,而且具有保值功能,對(duì)抗電流干擾效果明顯。
鋼制電纜橋架分為熱軋和冷扎鋼板,主要應(yīng)用于高速隧道、地鐵、輕軌等。一般可以使用三十年。
Cable bridge type selection navigation
1. Cable bridge product system
The cable tray product system includes: structural form, raw material and surface treatment.
The structure form includes: disc type, ladder type and slot type.
Raw materials include aluminum alloy, steel, FRP, and composite.
The surface treatment includes hot dip galvanizing, galvanizing, plastic spraying, galvanizing and spray molding.
Two. Application of cable bridge
The trough type cable bridge belongs to the closed cable bridge. The cable tray has a good effect on shielding and interference of cables, and is suitable for rain computer rooms.
The disc type cable tray has the characteristics of light weight and convenient heat dissipation, and is suitable for chemical industry, petroleum, telecommunication and television.
The ladder type cable tray has the characteristics of good annual heat dissipation and low cost, and is suitable for laying large diameter cables.
The aluminum alloy cable tray has light weight, and has the function of keeping value. It has obvious effect against current interference.
Steel cable tray is divided into hot rolled and cold rolled steel plates, mainly used in high-speed tunnels, subway, light rail and so on. Generally, it can be used for thirty years.
